The answer isn't a number. It's a framework. Here's how to work it out for your specific business.
This is one of the most searched questions in ecommerce and one of the most poorly answered.
Most of what you'll find online is either too vague to be useful ("it depends on your goals") or too specific to be accurate ("start with $10 a day"). Neither of those answers actually helps you make a decision about your money.
So let's do this properly.
There's no universal right number for Meta ads spend. But there is a framework for working out what makes sense for your specific business, at your specific stage, with your specific margins. And that's considerably more useful than a dollar figure pulled from a blog written by someone who doesn't know anything about your store.
Start here: is your store actually ready for paid traffic?
Before we talk about how much to spend, we need to talk about whether to spend at all.
Because Meta ads are an amplifier. They take whatever is already happening on your store and make it happen faster and at greater volume. If your store is converting well organically, ads will bring more of the right people in and revenue goes up. If your store isn't converting, ads will send more people to a store that doesn't work and your cost per purchase climbs while your results stay flat.
More traffic to a store that isn't converting doesn't fix the problem. It just makes it more expensive.
So before you set a budget, check your conversion rate. Go to Shopify Analytics, then Overview. If your store is converting below one percent, paid traffic is not the answer yet. Fix the store first.
If your conversion rate is sitting at one to two percent or above and you're getting some organic sales, you're probably ready to test ads. Let's talk about how much.
The learning phase: what Meta actually needs from you
Here's something Meta doesn't explain clearly enough.
When you launch a new campaign, it goes into what's called a learning phase. During this period, Meta's algorithm is figuring out who to show your ads to in order to get the best results. It needs data to do that. Specifically, it needs roughly 50 conversion events (purchases) in a seven day period to exit the learning phase and start optimising properly.
Why does this matter for your budget? Because if your budget is so low that it can only generate a handful of purchases a week, your campaign never exits the learning phase. It stays in perpetual learning, never optimising, and your results stay inconsistent and usually disappointing.
This is one of the most common reasons small ecommerce brands decide ads don't work for them. It's not that ads don't work. It's that the budget wasn't high enough for the algorithm to learn properly.
So when you're working out your budget, you need to think about what it costs to generate 50 purchases in a week and whether your budget can support that.
Working out your minimum viable budget
Here's the maths. And yes, we're doing maths. Stay with me.
You need your cost per purchase to work out roughly what budget gets you 50 purchases in a week.
If you don't have cost per purchase data yet because you haven't run ads before, use this rough starting point. Your cost per purchase in Meta ads is typically two to three times your average product price for a cold audience with no existing data. So if your hero product sells for $60, you might expect a cost per purchase somewhere between $30 and $60 in the early weeks while the algorithm is learning.
That's a rough estimate and it varies significantly by industry, product, creative quality and competition. But it gives you something to start with.
To generate 50 purchases a week at a $40 cost per purchase, you'd need roughly $2,000 a week in ad spend. That's $8,000 a month. For most small ecommerce brands, that's not where you start.
So what do you do if you can't spend that much?
You start smaller and you accept that the learning phase will take longer. A budget of $30 to $50 a day (roughly $900 to $1,500 a month) is a reasonable starting point for a small ecommerce brand testing ads for the first time. At this budget, you're not going to hit 50 purchases in seven days. But you'll start accumulating data, you'll see which creative is getting traction, and you'll be able to make informed decisions about whether to scale.
The key word is test. At this budget you're not scaling. You're learning. And that's fine, as long as you know that's what you're doing.
The management fee question
If you're considering hiring someone to manage your ads, there's another layer to this calculation.
A management fee is a fixed cost. It doesn't change based on how well your ads perform. Which means it needs to come out of your margin, not your revenue, and the maths needs to work before you commit to it.
Here's a simple gut check.
Work out roughly how much gross profit your ads are generating each month. That's the revenue your ads bring in, minus the cost of making and delivering the products sold. If that number is comfortably higher than the management fee, you're in a good position. If it's close to the management fee or under it, the numbers don't stack up yet.
Meta ads management from The eCom Studio starts from $1,300 plus GST per month. For that to make financial sense, your ad spend needs to be at a level where it's generating enough margin to cover the fee and still leave you ahead. Generally that means a monthly ad spend of at least $2,000 to $3,000 alongside the management fee.
If your budget isn't there yet, that's not a reason not to do ads. It's a reason to either build toward that budget before bringing in management, or to start with a Pick My Brain session to get your account set up and structured properly before you hand it over.
What "scaling" actually means
Once you've been running ads for a few weeks and you have data showing what's working, scaling is about increasing spend on what's performing and cutting what isn't.
Most founders make the mistake of scaling too fast or across the wrong campaigns. A common rule is not to increase your budget by more than 20 to 30 percent at a time. Bigger jumps can push the campaign back into the learning phase and undo the optimisation you've already built up.
Scaling also isn't just about budget. It's about creative. More budget going to a tired creative that's fatiguing won't improve results. More budget going to a fresh creative that's performing will. Which is why creative volume matters as much as spend level when you're trying to scale.
A rough guide by stage
Every business is different. But here's a general framework based on where you're at.
Just starting, testing for the first time.
$30 to $50 a day. Focus on one campaign, one objective (purchases), your best two to three creatives. Goal is to accumulate data and find what works, not to scale.
Getting some results, want to grow.
$50 to $100 a day. Start testing more creative variations. Look at what your cost per purchase is telling you. If it's profitable, consider increasing budget gradually.
Ready to scale.
$100 a day and above. Multiple creative variations across the funnel. Retargeting running alongside prospecting. Regular creative refreshes. This is where management support starts to make more sense because the account needs more active attention.
The honest answer to the question
How much should you spend on Meta ads?
Enough for the algorithm to learn. Enough that a management fee makes financial sense if you're bringing someone in. Enough that you can run proper creative tests rather than putting all your budget behind one or two ads and hoping.
For most small ecommerce brands starting out, that's somewhere between $900 and $1,500 a month in ad spend as a starting point. With the expectation that you're in learning mode, not scaling mode, until you have data to work with.
And if your store isn't converting organically yet, start there first. Fix the store. Then run the ads.
